Be it known that l 4CM1-annoia lll'. Com MAN, a citizen of the UnitedStel and e resident-oli *l'Vesteldr7 Union county, State of New Jersey,have invented eei'tein new sind useful Improvements in CerCon ticlli1ig.flip-- paratus, of which the following is e speeiiiczt tion.

This invention relates to new improved epparatus for automaticallycontrolling the movement of a caff.

The invention seeks to provide sin er1-enge mentwhereby the cer may heautomatically stopped 01 have its speed cheeked el be other Wisecontrolled when the track in advance in e condition of cle-ngen It alsoseeks to eeeomplish nl; hy Ineens which are sie@` le in eonstizuetienand effective in operation,

41 is a branch circuit including the circuitcontroller 42 and having oneend connected to track-contact and its other end connected to one of therails of section 30. vlcircuitcontroller 42 is connected to theup-anddown rod 43 of section 38, so as to be operated thereby.

The operation of the apparatus is as follOWS: When the engine is runningciong the trackv and before it reaches track-contact 40, switch 10 isclosed by having its plate 14 resting on contacts 15 and 16. The circuitthrough magnet '8 is therefore closed and the magnet is energized, sothat steam is supplied from the boiler of the'engine and `the airbrakesare cut off. When the train reaches the track-contact 40, the brushes17strike the contact 40, so as to make an electrical connection with itand at the same time elevate the plate 14 above contacts 15 and 16. lhisbreaks the magnet-circuit at thesefcontactf the progress of the trainwill not Le inten fered with. On the other hand, if tracksection 31 isoccupied by a train or is other- Wise in a condition of danger thesignal 38 Will be at danger and circuit-controller 42 ,open. In thiscasemagnet 8 will be denergi'ze'd to shut ofi the steam and put on theairebrakes. If for any reason the engineer does not Wish his train to bestopped by the danger condition of signal 38 or by the danger conditionof track-section 31, lie may operate switch 25, thereby closing tliecircuit of battery 9 through magnet 8 and wires 26 and 27. This willkeep magnet 8 still energized and prevent the application of theairbrakes and the vshutting oil' of steani-prcs sure. This movement ofthe switch 25 also operates Whistle 28.

It Will be observed that the progress of the train is automaticallycontrolled from the section in advance of the train. It will also beobserved that the use of a controlling-niagnet normally energized isespecially advantageous, inasmuch as a failure of the apparatus to Workproperly would' denergize the magnet' and stop the train. In otherwords, errors Would be on the side of safety. In Fig. 3 the magnet 8 isshown as employed to operate a signal on thecar. 44 and 45 are electriclamps, the latter being preferably red in color and connected in circuitwith generator 46 and circuit-controller 47, operated by magnet S. Whenmagnet 8 is eitprgized, lamp 45 is cut into circuit and lftrack-section- 31 is in a condilamp` 44 is cut out. When magnet 8 is de'q;

energized in the manner heretofore described, lamp 45 is cut out andlamp 44 is cut into Circuit at its circuit-controller 46 to Warn theoperator on the car.' lf desired, the control of the car may beaccomplished by means of the signals such as 44 and 45 and without themeans for automatically stopping tlie car. Buchan arrangement would benovel and useful and within the scope of the invention. Instead of lamp45 a Whistle may be used to sound when magnet 8 is deenergized.

lt is to be understood that the present invention is applicable to carspropelledly electricity or any other motive power. It is also to beunderstood that this invention is not limited tothe precise details in'structure or arrangement herein specifically shovin and descriloed. 'lhese may be widely varied without departing from the scope oftlienvention.
